    Abstract - (Show below) - (Hide below)

    Specifies the uniform requirements for the radio disturbance level of specified information technology equipment by fixing limits of disturbance, describing methods of measurement and standardizing operating conditions and interpretation of results. This Standard is identical to and has been reproduced from CISPR 22:1997.

    Scope - (Show below) - (Hide below)

    This publication applies to ITE as defined in 3.1.Procedures are given for the measurement of the levels of spurious signals generated by the ITE and limits are specified for the frequency range 9 kHz to 400 GHz for both class A and class B equipment. No measurements need be performed at frequencies where no limits are specified.The intention of this publication is to establish uniform requirements for the radio disturbance level of the equipment contained in the scope, to fix limits of disturbance, to describe methods of measurement and to standardize operating conditions and interpretation of results.
